Yeah, GK is a terrain map, completely different from the normal Graal style.
And Zero, I don't think it would be very laggy at all. I mean, that's like 1 extra character per tile to load. 64 extra characters would not take very long to load. That's not even 1 KB worth. It wouldn't even be noticeable. Now, depending on how it's done, it might 'cause some lag on gmaps, especially very large gmaps, but I know Stefan is smart enough to overcome that.
